QUEBEC CITY – Ryan Jimmo showed UFC fans his best robot dance, which meant he had another good night in the octagon.

After struggling with Sean O'Connell’s pressure, Jimmo freed himself to uncork a right hand that brought him a KO and a chance to show off his stuff.

The light heavyweight bout was part of the preliminary card of today’s TUF Nations Finale event at Colisee Pepsi in Quebec City, Quebec, Canada. It aired on FOX Sports 1 following additional prelims on UFC Fight Pass and ahead of a main card on FOX Sports 1.

The fight came to a crashing halt at the 4:27 mark of the first round when referee Dan Miragliotta pulled Jimmo off the unconscious O’Connell.

Jimmo admitted having trouble finding his range early in the fight when O’Connell intercepted his wild strikes and stuffed him against the cage. But he rebounded in a big way late in the frame after taking an illegal knee and trying unsuccessfully to take the fight to the mat.

O’Connell was in the midst of chasing down another clinch when he ran straight into Jimmo’s right hand. A few follow up punches from the Canadian were academic.

Jimmo (19-3 MMA, 3-2 UFC) gets back to the win column following a setback against Jimi Manuwa in his previous outing, but continues to hopscotch between wins and losses following his seven-second KO of Anthony Perosh that brought his first robot dance. O’Connell (15-5 MMA, 0-1 UFC), who stepped in for an injured Steve Bosse, sees a six-fight regional streak snapped.
